RADIATOR.

SPECIFICATION forming part of Letters Patent No. 493,590, dated March14, 1893.

Application tiled May 3, 1892. Serial No. 431,654. (No model.)

To aZZ whom t may concern:

Be it known that I, JAMES H. HU'roHINsoN, a citizen ofthe United States,residing in the cit y, county, and State of New York, have inventedcertain new and useful Improvements in Radiators; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in radiators and in valvestherefor.

The objects of the inventions are to secure large radiating surface,great strength, free circulation and simplicity in structure.

To these ends, the invention consists in the combinatoin of a radiatorhaving inlet and outlet ports and a compound stop and check valveconsisting of a valve casing divided by a diaphragm into two chambers orpassages, a stop valve in one chamber and a check valve in the other.

It also consists in the combination of a plurality of radiator sectionshaving circulating conduit and inlet and outlet ports at the bottomthereof, couplings having passages to correspond and register with theradiator ports and a compound stop and check valve whose A casing isprovided with passages corresponding with the radiator ports andcoupling passages.

It also consists in other combinations hereinafter described andclaimed.

In the drawings, Figure 1, is a central vertical section through myimproved radiator showing the radiator sections, the couplings and oneform of Valve. Fig. 2, is a central vertical section through one of theradiator sections. Fig. 3, is a horizontal section showing a series ofradiator sections connected together and thus showing the horizontaloutline of the sections. Fig. 4, is a view of one of the nipplecouplings. Fig. 5, is a sectional view of a second form of valveinvolved, and Fig. 6, is also a section showing how the check valve ismounted.

Referring to the drawings, lis the radiator section provided with ahorizontal opening a, divided by a diaphragm 2, a central verticalpassage or conduit b and side passages c c. The opening ct above thediaphragm communicates with ct below the diaphragm. The

lower ends of the radiator sections are thickened and provided withsockets 3 4 having right and left hand screw threads respectively, toprovide for coupling them together by means of the nipple couplings 5.These couplings are cast with diaphragm 6 corresponding and registeringwith the diaphragms 2 in the radiator sections and form a continuationof the same. The walls of the passages b and c c are centrally convex ontheir adjacent sides and at their upper corners on one side they areprovided with lugs 7 which bear against the next adjacent section andserve as spacing blocks to hold the radiator sections a proper distanceapart. The series of sections to constitute a practical radiator arebound together at the top by means of tie rods 8. The passage from thevalve casing to the first radiator section is of greater capacity thanthose between the diiferent sections, that a full head of steam or watermay pass freely through valve and thus provide for free circulationthrough the radiator. The valve casing has a diaphragm 10 which abutsagainst and registers with the diaphragm in the adjacent part. Thediaphragm divides the Valve casing into two chambers or passages 11 and12, in one of which is arranged a stop or globe Valve 14 and in theother of which is acheck valve 16. In the forms shown in Fig. 5, thevalve casing shows opening 18 for connection with main supply and 19 forconnection with a separate return pipe.

The valve casing is provided with aplug 17 to provide for grinding thevalve seat, with plug l5 to provide for the introduction of the valveand with another plug 2O to provide a socket 21 and for the boring ofanother socket 22 for the axis of the valve. Any number of radiatorsections may be assembled, the diaphragms of the diiferent partsregistering with each otherto form a continuous partition. The socket inthe outside of the last section is stopped by a suitable plug.

In operation, the stop valve 14 being open, the water or steam takes thecourse indicated by the arrows, first entering the horizontal passageabove the diaphragm, then upward through a central passage, and thencedownward through the side passages into passage below the diaphragm andthence through valve casing to source of supply.

IOO

Having now described my invention, what I claim is- 1. A radiatorsection having horizontal inlet and outlet passages at the bottom, avertical central circulating passage com municating with the inletpassage and vertical return passages communicating with the centralpassage and the outlet passage, the inlet and outlet passages beingformed by a diaphragm across an opening having a circular socket ornipple for screw coupling, substantially as described.

2. The combination of a series of radiator sections, having horizontalinlet and outlet passages formed by a diaphragm across an openingadapted for screw couplings, and couplings also having a diaphragmacross a passage therethrough, the diaphragms of the respective partsregistering with each other to form continuous inlet and outlet passagesthrough the radiator, substantially as described.'

3. The combination with the first of the radiator sections, of a valvechamber having inlet and outlet passages formed by a diaphragmregistering with the diaphragm ofthe next succeeding section and thestop valve for controlling the ingress of fluid to the register and thecheck valve, whereby its egress is controlled, substantially asdescribed.

4. A compound valve for radiators consisting of the combination of acasing, an inlet passage, a stop or globe valve to close said passage,an outlet passage, a check valve in said passage and coupling socketarranged to register the passages with those of its complement,substantially as described.

In testimony whereof I aftix my signature in the presence of twowitnesses.
